In a large series of patients who developed intracranial hematomas requiring emergent decompression, more than half had lucid intervals and were able to make conversation between the time of their injury and subsequent deterioration. In a more comprehensive review of the literature on the surgical treatment of acute subdural hematomas, lucid intervals were noted in up to 38% of cases.

These patients may be more likely to benefit from medical and surgical intervention when instituted in a timely fashion (ie, before further neurological deterioration). See Treatment, as well as the Medscape Reference article Head Injury.
